You know, I've always wondered if it wouldn't have helped to release the films only one year apart, like the Lord of the Rings films did. Obviously this would have been impossible, but I've always found that the PT is really bolstered when you watch it together, as a whole trilogy, rather than as individual films. That's one of the things that I think the OT really has going for it is that each film is not as dependent on the previous films. Not nearly as much carries over from film to film which, with a three year wait between films, would make them easier to enjoy. I say this because the first time I watched the films, I watched them back to back to back, etc. So I really got to see the entire trajectory of Anakin's arc in one go, essentially. It really helped me, personally, to get into the films. You realize a lot of things when you view them like that -- Palpatine's machinations for one, since you can see how he had been planning his coup for over a decade. That's just something I wondered about, anyway.
